What is the difference between a class and an object ?
- A class is a blueprint or template that defines the properties and behaviors of an object. An object, on the other hand, is an instance of a class. You can create multiple objects based on a single class definition.

How does Automatic Reference Counting (ARC) work in iOS?
- ARC keeps track of the number of references pointing to an object. Each time a reference to an object is created, ARC increases the reference count. When a reference is no longer used or goes out of scope, ARC decreases the reference count. When the reference count reaches zero, ARC automatically deallocates the memory occupied by the object.

#QA
When memory leaks may occur in Swift?

1. Strong reference cycles: When two objects hold strong references to each other, neither object can be deallocated because their reference counts never reach zero. This commonly happens when two objects have a property that holds a strong reference to each other.

2. Closures and capture lists: Closures capture and retain references to variables and objects they use within their body. If a closure captures a strong reference to an object that also holds a strong reference to the closure, a retain cycle can occur.

3. Delegate and callback patterns: If an object sets itself as the delegate or provides a callback closure to another object, and that object retains a strong reference back to the delegate or callback closure, a retain cycle can happen.

#QA
To prevent memory leaks in Swift, you can use the following approaches:

1. Weak and unowned references: Use weak or unowned references instead of strong references when there is a possibility of a retain cycle. Weak references allow the object to be deallocated, while unowned references assume that the object will always exist.

2. Capture lists: Use capture lists in closures to specify the relationship between the closure and the captured values. By using [weak self] or [unowned self] in the capture list, you can break retain cycles in closures.

3. Weak delegates: Declare delegate properties as weak to avoid strong reference cycles between objects.

#QA
Explain the concept of protocols in Swift.
- In Swift, protocols define a blueprint of methods, properties, and other requirements that a class, structure, or enumeration can conform to. They define a set of rules or contracts that specify what functionality should be provided. Protocols allow for defining reusable code, promoting code modularity, and enabling objects of different types to interact through a common interface.

maybe this is a transition period, I don't know, but now there is no time for anything, there are too many things to do at work. keep supporting me. I’ll be back soon In Shaa Allah

Insight:
"Understanding and applying SOLID principles in iOS development not only leads to cleaner, more maintainable code but also makes your apps easier to scale. By focusing on single responsibility and proper dependency injection, you can significantly reduce technical debt over time."

Insight:
"Leveraging SwiftUI's declarative syntax can drastically reduce the amount of boilerplate code in your iOS apps. By focusing on reusable components and state management, you can create dynamic, responsive interfaces with less effort and fewer bugs."

Insight:
"Investing time in unit testing is crucial for long-term project success. Tests not only catch bugs early but also give you confidence when refactoring. A well-tested codebase is more stable, easier to maintain, and safer to extend."

Insight:
"Properly implementing Clean Architecture in iOS apps can help manage complexity as your project grows. By separating concerns and creating clear boundaries between layers, you can keep your codebase organized and adaptable to changes."

Insight:
"Prioritize readability over cleverness in your code. Code is read more often than it's written, so always aim for clear and understandable solutions. A simple, straightforward approach is usually better than a complex one that’s hard to follow."

Insight:
"Using the MVVM pattern in iOS development can help you separate your app’s logic from the UI layer, making your code more testable and maintainable. By keeping the ViewModel clean and focused on business logic, you ensure a clear separation of concerns."

Insight:
"Async/Await in Swift simplifies asynchronous code by making it more readable and easier to maintain. By adopting these modern concurrency features, you can improve the performance of your app and reduce the complexity of handling asynchronous tasks."

Insight:
"Consistent naming conventions are essential for clean code. Use denoscriptive, meaningful names for variables, functions, and classes. Good names should reveal intent, making your code easier to understand without requiring extensive comments."

- Consistency: Stick to a consistent pattern throughout your codebase to make it easier for others (and yourself) to understand and maintain.
